Three Stooges [Moe Howard; Larry Fine; Curly Joe DeRita]; King Arthur; The Dirty Gray Knight; Merlin; Whammy (witch)
In Ye Olden Days, the Stooges take jobs as knights errant and are sent after The Dirty Gray Knight by King Arthur. Merlin fits them with armor with secret weapons and magic gimmicks built in. Blundering along, fighting knights and witches, turning into bats and conjuring a dragon, the Stooges manage to save the day.
A spaceship whisks the kids to the planet Glockenspiel, where the alien King takes on Orvie's face. The kids escape back to Earth, and the King is dragged along, where he fits right in with other monsters.
Three Stooges [Moe Howard; Larry Fine; Curly Joe DeRita]; convicts
Passing a prison, the Stooges are ambushed by escaped convicts who make them change clothes. In prison stripes, the boys are tossed in prison. But they escape and turn the tables on the crooks by mailing themselves as surprise packages.
